Question

At absolute zero temperature, a semiconductor acts as a conductor.

(a) True

(b) False

I got this question during an interview.

My query is from Classification of Metals, Conductors and Semiconductors topic in portion Semiconductor Electronics : Materials, Devices and Simple Circuits of Physics – Class 12

Answer 1

Correct answer is (b) False

The explanation: At absolute zero temperature, a semiconductor does act as an insulator. When the electron gains enough energy to participate in conduction, the electron is at a low energy state. Therefore, the semiconductors pretend like an insulator.
